ABSTRACT

Systems and methods are provided for blocking charges from a merchant to a payment account of a user. An exemplary system may include one or more memory devices storing instructions and one or more processors configured to execute the instructions to perform various operations. The operations may include receiving, from the user, a dispute request to dispute a charge to the payment account applied by the merchant. In response to the dispute request, the operations may include determining whether to block subsequent charges applied by the merchant to the payment account, based on a history of charging activities of the merchant. Responsive to a determination to block subsequent charges, the operations may include adding the merchant to a block-charge list associated with the payment account.

TECHNICAL FIELD

The present disclosure relates to systems and methods for blocking charges from a merchant to a payment account.

BACKGROUND

Payment cards such as credit cards have been widely used nowadays to facilitate financial transactions. Many people use credit cards to make automatic payments for utility bills, membership dues, newspaper/magazine subscriptions, online services, and other periodic charges. For example, a credit card customer may provide his/her card information to a merchant. The merchant then saves the card information in a bill processing system and charges the card every billing cycle (e.g., every week, month, quarter, year, etc.).

While this automatic payment process provides convenience to the customer, it may also cause problems when, for example, the customer decides to discontinue the automatic payment. In some cases, even if the customer has notified the merchant to stop charging the card, some merchants may continue charging the card using the stored card information. In current payment card systems, the customer must dispute every individual unauthorized charge, after the merchant makes that unauthorized charge, or, must close the card account all together. This causes great inconvenience to the customer.

Thus, there is a need for systems and methods capable of preventively blocking charges from a merchant to a card user's payment account.

Computing system 200 when implemented in merchant system 120 may include any hardware and/or software installed therein necessary for performing methods and processes of the disclosed embodiments.

The following processes are directed to various embodiments for blocking charges from a merchant to a payment account of a user. As used herein, the term “block” refers to a real-time or near real-time decline or rejection of a transaction authorization request initiated by a merchant (e.g., a merchant associated with merchant system 120) to charge a user's payment account (e.g., user 110's payment account associated with payment card 114). In this disclosure, the term “block,” “decline,” and “reject” are used interchangeably.

In some cases, a merchant may initiate a transaction authorization request to charge a user's payment account based on saved or stored payment account information. For example, user 110 may provide payment account information associated with payment card 114 (e.g., credit card number, expiration date, billing address, account holder name, “card verification value (CVV)” number, etc.) to a merchant (e.g., a sports club) to start a free trial of a service (e.g., gym membership). The merchant may then save the payment account information in their system. Toward the end of the trial period or after the end of the trial period, the merchant may charge membership fees using the stored payment account information. User 110 may wish to discontinue the membership. For example, user 110 may inform the merchant to cancel the membership and stop any pending or future payment. For various reasons, the merchant may continue charging user 110's payment account using the stored payment account information. After each charge is made, user 110 may dispute the charge by communicating with the financial service provider, e.g., the card issuer. The financial service provider may then investigate the charge and credit the charged amount back to user 110's payment account if the charge is indeed unauthorized. If the merchant again makes such similar charges to user 110's payment account, user 110 may have to undergo the dispute process again for each of the charges. In other words, the conventional dispute process is an “after-the-fact” remedial method, which is not capable of preventing the merchant from making future or subsequent charges to the payment account, even though in some cases future occurrences of such unauthorized charges are highly probable.

Systems and methods disclosed in this application may preventively block future or subsequent unauthorized charges from a particular merchant based on certain criteria. In other words, embodiments disclosed herein provide “before-the-fact” preventive methods to relieve user 110 from undergoing repeated dispute procedures. In some embodiments, once a particular merchant has been identified as making repeated unauthorized charges to user 110 or to a group of users in general, the merchant can be flagged or tagged (e.g., added to a block-charge list associated with user 110's payment account), such that future charges from that merchant to the payment account of user 110 would be automatically blocked.

In some embodiments, FSP system 130 may be configured to block subsequent charges from a merchant to user 110's payment account after user 110 files a dispute against the merchant regarding a charge previously applied or charged by that merchant to his/her payment account. In particular, the processes of some embodiments implement a reputation-based block-charge list to prevent a particular merchant from charging the user's payment account once that merchant has been added to the block-charge list.

The following processes are exemplary implementations of blocking unauthorized charges initiated by a merchant. These processes may be performed by various aspects and components of system 100 and computing system 200, as is apparent from the disclosure.

FIG. 3 is a flowchart of an exemplary process 300 for blocking charges from a merchant to a payment account of a user, such as user 110, consistent with disclosed embodiments. In step 310, FSP system 130 may receive a dispute request from user 110 to dispute a charge to user 110's payment account applied or charged by a merchant, such as the merchant associated with merchant system 120. In some embodiments, user 110 may file the dispute request by calling a customer service number of the financial service provider associated with FSP system 130 (e.g., the card issuer of user 110's payment card 112). In this case, a customer service representative may communicate with user 110 to obtain dispute information such as merchant name, transaction or charge details (e.g., date, amount, location, etc.), reason for the dispute, etc., and input the dispute information into FSP system 130. After receiving the dispute information, FSP system 130 may process the dispute information and provide feedback to the customer service representative if an option is available for blocking subsequent charges from the merchant to user 110's payment account. In some embodiments, user 110 may file the dispute request through an online portal, for example, a website of the financial service provider or a mobile application. For example, user 110 may identify a transaction applied by a merchant for dispute from his/her payment account activities using the website or mobile application, and select a dispute option to initiate the dispute request. User 110 may input dispute information through the online portal and submit the dispute request along with the dispute information to FSP system 130. FSP system 130 may process the dispute information and may inform user 110 when an option is available for blocking subsequent charges from the merchant.

In step 320, FSP system 130 may, in response to the dispute request, determine whether to block subsequent charges initiated by the merchant to user 110's payment account based on a history of charging activities of the merchant. For example, FSP system 130 may identify the merchant based on the dispute request. The dispute request may include a transaction charged by the merchant, and may include merchant information such as merchant name, merchant ID, merchant address, merchant phone number, etc. Based on such information, FSP system 130 may identify the merchant. In some embodiments, the merchant information may be input to FSP system 130 when, for example, the dispute is filed by user 110 through calling a customer service number of the financial service provider and communicating with a customer service representative. In this case, the customer service representative may input the merchant information into FSP system 130.

After FSP system 130 identifies the merchant, FSP system 130 may determine a history of charging activities of the merchant. In some embodiments, the history of charging activities may include a total number of dispute requests received against the merchant. In this case, FSP system 130 may search a dispute database (e.g., part of database 135 or 240) using the merchant's identification information and identify dispute requests filed by multiple users against the merchant. The search may provide a total number of dispute requests filed against the merchant based on one or more criteria, such as over a predetermined period of time, within a set geographic area, for a particular category of goods/services, whether the merchant won or lost the disputes, the disputed charge amounts, etc. For example, FSP system 130 may obtain a total number of dispute requests filed by users living in a city against the merchant in the past two years. In another example, FSP system 130 may obtain the total number of dispute requests filed against the merchant and the merchant lost in those disputes. In another example, FSP system 130 may obtain the total number of dispute requests filed against the merchant disputing membership fee charges. Other criteria or combinations of criteria may also be used depending on particular situation.

After FSP system 130 obtain the total number of dispute requests subject to one or more suitable criteria, FSP system 130 may compare the number with a predetermined threshold. If the number exceeds the predetermined threshold, FSP system may determine to block subsequent charges applied or initiated by the merchant to user 110's payment account. For example, the predetermined threshold may be 10, 20, or any suitable number.

In some embodiments, instead of or in addition to obtaining the total number of dispute requests filed against the merchant by multiple users, FSP system 130 may search the dispute database and identify the number of dispute requests filed by a particular user, such as user 110 who files the dispute request in step 310. In this case, FSP system 130 may evaluate whether the merchant repeatedly makes unauthorized charges to user 110's payment account. FSP system 130 may obtain the number of dispute requests against the merchant received from user 110 based on similar criteria as discussed above.

After FSP system 130 obtain the number of dispute requests received from user 110, subject to one or more suitable criteria, FSP system 130 may compare the number with another predetermined threshold. If the number exceeds the predetermined threshold, FSP system may determine to block subsequent charges applied or initiated by the merchant to user 110's payment account. For example, the predetermined threshold may be 3, 5, or any suitable number of dispute requests. In some embodiments, the predetermined threshold used for comparing with the number of dispute requests received from user 110 may be lower than the predetermined threshold used from comparing with the total number of dispute requests received from multiple users.

In some embodiments, the history of charging activities may include a number of repeated charges applied by the merchant to user 110's payment account. For example, FSP system 130 may search the dispute database for those disputes against the merchant where the disputed charges are repeated charges. The repeated charges may have similar amounts, charged repeated according to certain charging cycles, or resemble other types of similarities. For instance, the merchant may charge user 110 membership fee every month using his/her credit card information stored on the merchant's billing system, despite the fact that user 110 has cancelled the membership. User 110 may have disputed the monthly charge every time. This pattern of repeated charging and disputing activities may be obtained from user 110's account activity history and used by FSP system 130 as a basis for blocking merchant from making subsequent charges. For example, if the number of repeated charges exceeds a predetermined threshold, FSP system 130 may determine to block subsequent charges initiated or applied by the merchant.

After FSP system 130 determines to block subsequent charges from the merchant (step 320: Yes), FSP system 130 may add the merchant to a block-charge list associated with user 110's payment account in step 340. For example, FSP system 130 may determine a merchant identifier, such as the merchant's name, a merchant code, a phone number of the merchant, an address of the merchant, or other data that identifies the merchant. FSP system 130 may determine the merchant identifier based on the dispute request, merchant record (e.g., from client data 234, stored in database 240 or 135), the history of charging activities, etc. FSP system may then add the merchant identifier to the block-charge list. The block-charge list may be associated with individual user's payment account. For example, each user may has his/her own block-charge list including one or more merchants that previously made unauthorized charges to that user's payment account and underwent at least one dispute process. In some embodiments, a merchant may be removed from the block-charge list after a predetermined period of time, such as 6 months, 1 year, etc.

In some embodiments, user 110 may be provided with a choice to accept or decline the option of blocking subsequent charges from the merchant. For example, FSP system 130 may inform a customer service representative about the blocking option, and the customer service representative may communicate with user 110 about the option and obtain user 110's verbal confirmation about whether to accept or decline the option. The customer service representative may then input the user's choice to FSP system 130. FSP system 130 may then add the merchant to the block-charge list after receiving the confirmation that user 110 accepts the blocking option. In another example, FSP system 130 may provide instructions to user device 112 for displaying an application user interface to receive user input as to whether to accept of decline the blocking option. After receiving user input indicating the user 110 accepts the blocking option, FSP system 130 may then add the merchant to the block-charge list associated with user 110's payment account.

If FSP system 130 determines not to block subsequent charges from the merchant (step 320: No), FSP system 130 may process the dispute request according to any known methods without blocking subsequent charges from the merchant, as shown in step 330.

FIG. 4 is a flow chart of an exemplary process 400 for blocking a charge from a merchant that is on the block-charge list associated with a payment account of a user, such as user 110. In step 410, FSP system 130 may receive a transaction authorization request for charging user 110's payment account. For example, the merchant associated with merchant system 120 may initiate the transaction authorization request charging user 110's payment account using the account information saved on merchant system 120. The transaction authorization request may be initiated at merchant system 120 and received by FSP system 130 through transaction processing network 145 and/or network 140.

After receiving the transaction authorization request, FSP system 130, in step 420, may determine whether the transaction authorization request is initiated by a merchant listed on the block-charge list. FIG. 5 shows an exemplary implementation of step 420. Referring to FIG. 5, FSP system 130 may determine a merchant identification code based on the transaction authorization request in step 422. The merchant identification code may include any form of identification information that identifies the merchant that initiates the transaction authorization request. For example, the merchant identification code may include the merchant name, merchant code, merchant phone number, address, etc. In step 424, FSP system 130 may compare the merchant identification code with the merchant identifier(s) in the block-charge list and determine if the merchant identification code matches any merchant identifier on the block-charge list. If a match is found (step 424: Yes), the process proceeds to step 428, in which FSP system 130 may determine that the transaction authorization request is initiated by one of the merchants in the block-charge list. If the merchant identification code does not match any merchant identifier on the block-charge list (step 424: No), the process proceeds to step 426, in which FSP system 130 may determine that the transaction authorization request is not initiated by any merchant in the block-charge list.

Returning to FIG. 4, if FSP system determines that the transaction authorization request is initiated by a merchant listed on the block-charge list (step 420: Yes), then process 400 proceeds to step 440, in which FSP system 130 may decline the transaction authorization request, therefore blocking the merchant's charging request and preventing the merchant from making any subsequent charges to the user's payment account. If FSP system determines that the transaction authorization request is not initiated by any merchant in the block-charge list (step 420: No), then process 400 proceeds to step 430, in which FSP system 130 may process the transaction authorization request according to any known methods, including approving the transaction authorization request.

FIG. 6 is a flow chart of another exemplary process 600 for blocking payments to a merchant from a payment account of a user, such as user 110. In step 610, FSP system 130 may receive a dispute request from user 110 to dispute a charge to user 110's payment account applied or charged by a merchant. Step 610 is similar to step 310. In step 620, FSP system 130 may determine whether the merchant's reputation score is below a predetermine threshold. A reputation score may be used to measure the reputation of a merchant in terms of its tendency to make unauthorized charges. The reputation score may take any suitable form, such as a number ranging from 0 to 100 or 1 to 5, or a letter score from A to F, and may include half step indicators such as “+” and “−”. For example, a score of 100, A, A+, 5, etc., may indicate that the merchant has an outstanding reputation and may never receive dispute requests against it or may never lose any dispute. On the other hand, a score of 0, F, F−, 1, etc., may indicate that the merchant has a high risk of making unauthorized charges and may receive a large number of disputes against it or may lose a large number of disputes. In some embodiments, the reputation score may be determined based on the total number of dispute requests received against the merchant, where a higher total number of dispute requests corresponds to a lower reputation score. In some embodiments, the reputation score may be determined based on the number of disputes received from a particular user, such as user 110, against the merchant, where a higher number of dispute requests corresponds to a lower reputation score. In this case, the reputation score of a merchant may be individually determined for each particular user.

In some embodiments, after receiving the dispute request in step 610, FSP system may update the reputation score of the merchant that is the subject of the dispute. For example, FSP system may adjust the reputation score based on the dispute received in step 610 (e.g., lowering the score). In some embodiments, FSP system 130 may update the reputation score periodically.

FSP system 130 may compare the reputation score of the merchant with a predetermined threshold to determine whether to add the merchant to a block-payment list, thereby blocking subsequent charges from the merchant to the user's payment account. The block-payment list is similar to the block-charge list discussed above. For example, the predetermine threshold may be set according to the specific form of the reputation score. If a reputation score is below the threshold, it may indicate that there is a relatively high risk that the merchant will make subsequent unauthorized charges to the user's payment account. Therefore, the reputation score and the threshold may be used by FSP system 130 to determine whether to add the merchant to the block-payment list to block subsequent payment to the merchant from the user's payment account. If the reputation score of the merchant is not below the predetermined threshold (step 620: No), process 600 proceeds to step 630, in which FSP system 130 may process the dispute without blocking subsequent charges from the merchant to user 110's payment account. Step 630 is similar to step 330. If the reputation score is below the predetermined threshold (step 620: Yes), process 600 proceeds to step 640, in which FSP system 130 may add the merchant to a block-payment list associated with the payment account of user 110. Step 640 is similar to step 340.

Similar to process 300, user 110 may be provided with a choice to accept or decline the option of blocking subsequent charges from the merchant. In some embodiments, FSP system 130 may add the merchant to the block-payment list after receiving confirmation from user 110 indicating the user 110 accept the blocking option.

After a merchant is added to the block-payment list according to its reputation score, subsequent charges initiated by the merchant to request payment from the user's payment account may be automatically declined. For example, process 400 discussed above in connection with FIGS. 4 and 5 may be used to process and/or block subsequent transaction authorization requests charging the user's payment account.

FIGS. 7A-7D show a series of exemplary application interfaces that are configured to allow a user 110 to accept or decline the option of blocking subsequent charges from a merchant. The exemplary application interfaces may be part of a mobile application installed on user device 112, or may be implemented as part of a website or web portal that can be accessed by user 110 using a browser software application.

FIG. 7A shows an interface displaying an alert message 712 informing the user that a dispute request against a merchant has been received and providing the user with an option to block additional charges from that merchant. In some embodiments, alert message 712 may be displayed on a lock screen 710 of user device 112, so that user 110 may receive the alert even if the user is not logged in to the mobile application or a website associated with the user's payment account. The user may be provided with a control option to block charges from the merchant by, for example, pressing the alert message, as shown in FIG. 7A. Specifically, after the user presses alert message 712, an interface shown in FIG. 7B may be displayed, in which a message 720 is provided to the user inquiring whether to block the merchant. The user may accept the blocking option by pressing button 722, or declining the blocking option by pressing button 724.

In some embodiments, the interface shown in FIG. 7B may be provided only after authentication of the user identity, for example, by verifying a password, a confidential graphical pattern, a fingerprint, a facial feature, etc. If the user selects button 722 to accept the blocking option, an interface shown in FIG. 7C may be displayed showing a message indicating that the request to block the merchant is being processed. After the merchant has been successfully blocked (e.g., added to the block-charge list or the block-payment list as discussed above), an interface shown in FIG. 7D may be displayed, and a message 740 may be displayed informing the user that the merchant has been blocked, as well as other related information such as the duration in which the blocking feature stays in effect.

The above-described processes may be implemented as a computer program or application or as a plugin module or sub-component of another application. Some of the described processes may be executed by a computing system 200 of FSP system 130, merchant system 120, user device 112 or other system provided as part of payment processing network 145. The described techniques may be varied and are not limited to the examples or descriptions provided.
